hi im having this code l = [1, 3, 5, 'D', 1, 2, 3, 4, 5, 6, 7, 'A', 'S', 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, 'A']
why i need to copy x list? can someone explain me. If i dont copy it i get this result: >>> took_num_range(l) [[1, 2, 3, 4, 5, 6, 7], [6, 5, 4, 3, 2, 1, 0], [6, 5, 4, 3, 2, 1, 0], [6, 5, 4, 3, 2, 1, 0], [6, 5, 4, 3, 2, 1, 0]] but if i copy it i get result as im looking for >>> took_num_range(l) [[1, 2, 3, 4, 5, 6, 7], [9, 8, 7, 6, 5, 4, 3], [8, 7, 6, 5, 4, 3, 2], [7, 6, 5, 4, 3, 2, 1], [6, 5, 4, 3, 2, 1, 0]] >>> def took_num_range(l): j = [] x = [] for i in l: if type(i) is int and len(x) == 7: j.append(x) x = x[:] # im mean here x.pop(0) if type(i) is int and len(x) < 7: x.append(i) if type(i) is not int and len(x) == 7: j.append(x) x = [] if type(i) is not int and len(x) != 7: x = [] return j thx -- http://mail.python.org/mailman/listinfo/python-list
